I don't share your view.
Company doing good thing without simultaneously promising it won't do bad thing doesnt automatically mean BAD THING WILL ABSOLUTELY SUPER DUPER CERTAINLY HAPPEN NEXT.
The opposite, actually.
When corpos are specific about bad thing definitely not being planned, that's when it is DEFINITELY the next step.
Using a domain for your handle means it entirely replaces the original bsky handle you signed up with.
I could go from being
mentaledge.bsky.socialtomentaledge.com, for example. (And they don't need to be the same "username" so to speak, I could have registeredtherealmental.bsky.social, but then becomementaledge.com, provided I own the domain.)The main difference is that the orignal handle is a subdomain of bsky, while you can be the root domain if you use your own.
Before, you'd lose your original handle, meaning someone else could grab it once you did this, and then pretend to be you. Now they can't.
